| 摘 要： | 用经过改进的连续稀释法测定了尚未见报道的六个含环己酮二元体系在293.15K(及298.15K的过量体积,经与已知标准物系数据的比较,验证了实验方法的可靠性。所得实验数据用关联方程式进行拟合,得出了各体系的拟合参数值。以范德华方程为基础,推导了过量体积与过量焓的关联方程。根据这一方程,分析了压力和过量焓对估算过量体积的影响。

| Abstract: | Excess volumes of six binary systems containing cyclohexanone have been experlmenlally determined at 293.15K and 298.15K by eontinuous dilution method.The reliabllity of the method has been verified with measurements for the standard system with known data. The values of the parameters of the empirical correlation equation have been determined by data fkitting.Bssed on the van der Waals equation of state, an equation correlating VE directly with HE for binary systems has been derived. It can be used to predict VE from HE and the propertiies of pure components for any pressure. The effects of P and HE on pre- dicting VE have been analyzed. |
